Abstract

This paper presents an investigation on Burr Formation Height (BFH) and surface roughness (Ra) in Surface Grinding (SG) machining. The burr height and Ra in XW-42 alloy steel are studied as a function of machining variables, which are Depth of Grind (DOG), Wheel Speed (WS) and Number of Pass (TIME) to help illuminate the burr formation and Ra mechanisms. A series of Design of Experiments (DOE) with full factorial design was conducted to study the optimum parameters as a process function. The significance of the grinding parameters on the selected responses was evaluated using analysis of variance ANOV A Empirical grinding models were developed by using regression analysis which considered on the significant effect of input factors and the model will be used to obtain optimum output responses (theoretical result) set as optimum parameters. Subsequently, carry out experimental again based on optimum parameters to validate the model by comparing both theoretically result and experimental result. The range of the accuracy must be in a range of± 15% which is called marginal of error.
